Abstract

A snap-in assembly of a wallplate to a heat sink is achieved by placing notches in the ends of the heat-dissipating fins of the heat sink which receive in locking engagement the free ends of tabs placed along the inside of the peripheral wall, at the top and bottom ends, of the rear surface of the wallplate. The wallplate can be removed from the heat sink and reinstalled as desired.

Description

BACKGROUND OF THE INVENTION Field of the Invention
The invention is directed to wiring devices and more particularly to wallplates and heat sinks for use with such devices.
SUMMARY OF THE INVENTION
An assembly of a wallplate with a heat sink provides a snap-on mounting of a wallplate on the heat-dissipating fins of a heat sink. The heat sink comprises a base upon which are formed a number of heat-dissipating fins, each having a notch at both of its two ends. A wallplate has a body which includes a wall extending along the entire periphery of the back surface of the body. A tab is formed on the inside surface of the wall along a top and bottom portion of the wall. The tabs each terminate in a free end which can lockingly engage the notches at the ends of the heat-dissipating fins to hold the wallplate and heat sink in assembly. The snap-on wallplate can be removed from the heat sink and reinstalled as desired. It is an object of this invention to provide a novel snap-on wallplate and heat sink assembly.
It is an object of this invention to provide a novel snap-on wallplate and heat sink assembly which does not require any additional fixtures to join the wallplate and heat sink.
It is another object of the invention to provide a novel snap-on wallplate and heat sink that uses notches and tabs for assembly of the wallplate to the heat sink.
Other objects and features of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principles of the invention and the best mode which is presently contemplated for carrying them out.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning to FIGS. 1 to 11 there is shown an assembly 20 of a wallplate 22 with a heat sink 24. The wallplate 22 has a front surface 26 and a rear surface 28. A cut-out 30 permits operating devices such as the slider switch 32 to extend through the wallplate 22 so that they can be manipulated by a user.
The wallplate 22 has a wall 34 which extends about the entire periphery of rear surface 28 as is best seen in FIG. 6. At the top and bottom edges, 36, 38, respectively, the wall 34 includes a further tab 40, whose free end 42 (FIGS. 4 and 5) is used to lock the wallplate 22 to the heat sink 24, as will be described below. The periphery of wallplate 22 at front surface 26 is tapered as at 44.
Turning now to FIGS. 7 to 10, the details of the heat sink 24 are shown. Heat sink 24 has a base member 50 having a central portion 52 having apertures 54 to fasten the heat sink 24 to an operating system such as a slide dimmer (not shown). The central portion 52 also supports an operating device such as the slide switch 32 shown in FIG. 2. Slots 56, 58 and 60 permit the slide switch 32 to move along central portion 52 of the heat sink 24. Flanking the central portion 52 are a number of heat-dissipating fins 62 (see FIGS. 7 and 8). Shown are four heat-dissipating 62 to each side of central portion 52. The number of heat-dissipating fins 62 can be increased or decreased as desired. The joint between the heat-dissipating fins 62 and the base member 50 can be scored so that any heat-dissipating fins 62 not required can be broken off and removed.
At the top end 64 and the bottom end 66 of the heat-dissipating fins 62 is a notch 68 with a curved lead-in 70, as shown in FIGS. 9 and 10.
Referring now to FIG. 11 the assembly of wallplate 22 to heat sink 24 is now set forth. The wallplate 22 is made of a plastic material which is resilient, such as a thermoset or thermoplastic material such as nylon, which can be stretched but recovers to its original shape when the stretching forces are removed. The heat sink 24 is made of metal, such as aluminum which is relatively rigid. It is assumed that the heat sink 24 is assembled to an operating system such as a slide dimmer (not shown) which in turn is mounted to a gang box (not shown) as is well known in the art. The heat sink 24 position is thus fixed. The top edge 36 of wallplate 22 is aligned with the top end 64 of the heat sink 24. Although not shown, the bottom edge 38 of wallplate 22 is also aligned with the bottom end 66 of heat sink 24. Force is then exerted on front surface 26 of wallplate 22. This causes free end 42 of tab 40 to move along curved lead-in 70 stretching the tab 40 and wall 34. As soon as the free end 42 of tab 40 enters notch 68, the tab 40 and wall 34 return to their initial sizes thus firmly holding the free end 42 of tab 40 of wallplate 22 in notch 68 of the heat sink 24. A similar action occurs at edge 38 of wallplate 22. To remove the wallplate 22 from the heat sink 24, the wallplate 22 is gripped at top edge 36 and bottom edge 38 and pulled in a direction away from the heat sink 24. This permits the free end 42 to trace the wall of notch 68 in the direction of curved lead-in 70 and stretch the tab 40 and wall 34 until the free end 42 is entirely out of notch 68. The wallplate 22 can be reinstalled to the heat sink 24 again as above described.
While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiment, as is presently contemplated for carrying them out, it will be understood that various omissions and substitutions and changes of the form and details of the device illustrated and in its operation may be made by those skilled in the art, without departing from the spirit of the invention.
